Following the designs (https://linear.app/comm/issue/DES-27/view-media-for-chat), users should be
able to click "see more" to navigate from the thread settings media gallery to a full screen media
gallery. Using `ThreadSettingsCategoryHeader` didn't allow for a title and also additional text ("see
more"), so I made another component that takes an `onPress` and `actionText`. This way, we can navigate to
the full screen gallery when actionText is pressed. The next diff will implement the actual full screen
gallery.
